Interacting with your computer

Input devices are the pieces of hardware which allow us to enter information into the computer.

A standard PC keyboard has various groups of keys.

  • Alphanumeric keys - these represent letters and numbers, arranged as on a typewriter.

  • A numeric keypad appears to the right of the main keyboard and contains numeric and editing keys; the Num Lock key is used to switch from numbers to editing functions.

  • Function keys appear at the top of the keyboard and can be programmed to do special jobs.

  • Cursor keys include 'arrow keys' which move the insertion point, and keys such as Home, End, Page Up, and Page Down, which let you move around documents.

  • Dedicated keys are used to issue commands or produce alternative characters. For example: Ctrl changes the functions of other keys (e.g. Ctrl + X cuts the selected text).

Caps Lock sets the keyboard in 'CAPITALS' mode; it only affects letters.

Enter (or Return) is pressed to select options from a menu or to start a new paragraph.

Backspace deletes the character to the left of your current position.

The mouse

A mouse is a hand-held device that lets you move a pointer (or cursor) and select items on the screen. It has one or more buttons to communicate with the PC. A scroll wheel lets you move through your documents or web pages The pointer looks like an I-bar, an arrow or a pointing hand.

An optical mouse has an optical sensor instead of a ball underneath. A cordless (wireless) mouse has no cable; it sends data via infrared signals or radio waves. Mouse actions:

  • to click, press and release the left button.

  • to double-click, press and release the left button twice.

  • to drag, hold down the button, move the pointer to a new place and then release the button.

  • to right-click, press and release the right button; this action displays a list of commands.

Voice input

Today you can also interact with your computer by voice with a voice-recognition system that converts voice into text, so you can dictate text directly onto your word processor or email program. You can also control your PC with voice commands; this means you can launch programs, open, save or print files. Some systems let you search the Web or chat using your voice instead of the keyboard.

to copy images from paper into a computer

to read price labels in a shop

to select text and click on links on web pages

to enter drawings and sketches into a computer

to input voice commands and dictate text 1 to draw pictures or select menu options directly on the screen 8 to take and store pictures and then download them to a computer.

**Complete each sentence by choosing from the following devices: touch screen, trackball, touchpad, webcam.

1 A is a stationary device that works like a mouse turned upside down. You roll the ball with your hand to move the pointer on the screen.

2 Interactive are used in museums, information centres and Internet kiosks. You use your finger to point directly to objects on the screen.

3 ……………. is used to send live video images via the Internet.

4 A……………… is found on notebook PCs. You use it by pressing the sensitive pad with a finger.

** Label the groups of keys with terms from B opposite. Then identify the keys described below.

6 It produces upper-case letters, but it does not affect numbers and symbols.

7 It removes the character to the left of the cursor or any selected text.

8 It works in combination with other keys, e.g. you press this key and C to copy the selected text.

**Parts of a computer

A computer is an electronic machine that accepts, processes, stores and outputs information. A typical computer consists of two parts: hardware and software. Hardware is any electronic or mechanical part of the computer system that you can see or touch.

Software is a set of instructions, called a program, which tells a computer what to do. There are three basic hardware sections.

1 The CPU is the heart of the computer, a microprocessor chip which processes data and coordinates the activities of all the other units.

2 The main memory holds the instructions and data which are being processed by the CPU. It has two main sections: RAM (random access memory) and ROM (read only memory).

3 Peripherals are the physical units attached to the computer. They include: Input devices, which let us enter data and commands (e.g. the keyboard and the mouse).

Output devices, which let us extract the results (e.g. the monitor and the printer).

Storage devices, which are used to store information permanently (e.g. hard disks and DVD-RW drives). Disk drives are used to read and write data on disks. At the back of a computer there are ports into which we can plug external devices (e.g. a scanner, a modem, etc.). They allow communication between the computer and the devices

**Look at A opposite. Read these quotations and say which computer essential they refer to.

1. ‘Accelerate your digital lifestyle by choosing a Pentium at 4.3 GHz.’

2. ‘Right-click to display a context-sensitive menu.’

3. ‘You will see vivid, detailed images on a 17" display.’

4. ‘This will produce high-quality output, with sharp text and impressive graphics.’

5. ‘Use it when you want to let the grandparents watch the new baby sleeping.’

6. ‘Press any key to continue.’

**Match the terms with their definitions.

CD/DVD drive

Speaker

Modem

port

a any socket into which a peripheral device may be connected

b device used to produce voice output and play back music

c mechanism that reads and/or writes to optical discs

**Complete the diagram and sentences below with words from C opposite.

1 Computer is the visible or audible result of data processing – information that can be read, printed or heard by the user.

2 The CPU will process data as instructed by the programs you're running includes functions like calculating, sorting, editing, drawing and searching.

3 DVDs are expected to replace CDs as devices.

4 As a scanner, the Sigma-100 can be used to photographs as well as documents into the computer.

9 It is used to confirm commands; in a word processor, it creates a new paragraph.

**Look at C opposite. Complete these sentences with the correct 'mouse action'.

1 To start a program or open a document you ………….. on its icon - that is, you rapidly press and release the mouse button twice.

2 If you want to select a menu option, you just…………… on the left button.

3 If you want to find the commands for a particular text, image, etc., you have to ……………… on it.
